Ingredients

Tender, flourless cake packed with oranges, pistachios, and almond flour, then topped with sticky orange and honey on top.

For the Cake

  • 2 cups almond flour
  • 2 whole oranges
  • ⅔ cup honey
  • 3 large eggs
  • ½ teaspoon baking soda
  • 1 cup ground pistachios
  • 1 teaspoon vanilla extract

For the Glaze

  • 2 tablespoons honey
  • ½ cup fresh orange juice

How to Make Flourless Orange Pistachio Cake

Step 1: Prepare the Oranges

Take the oranges, rinse them well under running water, and toss them in a pot. Pour in enough water to cover them. Let them simmer gently for an hour.

Step 2: Blend the Oranges

Once boiled, drain the water and pop the oranges into a blender. Blend them until the texture is velvety smooth.

Step 3: Preheat the Oven

Set your oven to 350°F (175°C) and lightly grease a 9-inch springform pan so the batter won’t stick.

Step 4: Mix Ingredients

In a large mixing bowl, combine the blended oranges, honey, eggs, almond flour, ground pistachios, baking soda, and vanilla extract. Stir everything together until smooth.

Step 5: Bake the Cake

Pour the mixture into the greased pan and bake for around an hour. Keep an eye on it—if the top starts browning too early, loosely cover it with foil. It’s done when a toothpick comes out clean.

Step 6: Prepare the Glaze

Combine honey and orange juice in a small pot. Heat it up until it boils; then lower the heat and simmer it down to half its original amount. Let it cool afterward.

Step 7: Apply Glaze & Cool

Once the cake isn’t too hot, apply the glaze over the top using a brush. Let it cool completely before taking it out of the pan to enjoy.

How to Serve Flourless Orange Pistachio Cake

Serving Flourless Orange Pistachio Cake is all about enhancing its delightful flavors. This cake pairs wonderfully with various accompaniments that elevate its taste and presentation.

With Fresh Fruit

  • Citrus Slices: Add a refreshing touch by garnishing with thin slices of oranges or grapefruits.
  • Berries: Serve alongside strawberries, blueberries, or raspberries for a burst of sweetness and color.

With Whipped Cream

  • Coconut Whipped Cream: A dairy-free option that adds a light and creamy texture, complementing the cake’s rich flavors.
  • Honey Sweetened Cream: Blend heavy cream with a bit of honey for a slight sweetness that harmonizes with the cake.

As Part of a Dessert Platter

  • Cheese Selection: Pair with soft cheeses like goat cheese or ricotta to provide a savory contrast.
  • Nuts: Incorporate roasted almonds or more pistachios to add crunch and depth to your dessert spread.

How to Perfect Flourless Orange Pistachio Cake

Perfecting your Flourless Orange Pistachio Cake takes attention to detail. Here are some tips to ensure your cake turns out beautifully every time.

  • Use Fresh Oranges: Opt for fresh oranges rather than bottled juice for the best flavor in both the cake and glaze.
  • Check Oven Temperature: Always use an oven thermometer to ensure accurate baking temperatures for even cooking.
  • Leave It to Cool: Allow the cake to cool completely in the pan before removing it. This helps prevent breakage.
  • Don’t Overmix: Mix just until combined to maintain a light texture; overmixing can lead to a dense cake.
  • Experiment with Toppings: Feel free to top the cake with additional pistachios or orange zest for added flavor and visual appeal.

Best Side Dishes for Flourless Orange Pistachio Cake

Pairing side dishes with your Flourless Orange Pistachio Cake can enhance your dining experience. Here are some delicious options that complement it well.

  1. Greek Yogurt: Creamy and tangy, Greek yogurt adds richness and pairs excellently with the orange flavor.
  2. Chocolate Sauce: A drizzle of dark chocolate sauce provides an indulgent contrast to the citrus notes in the cake.
  3. Fruit Salad: A mix of seasonal fruits adds brightness and freshness, balancing the richness of the cake.
  4. Nutty Granola: Serve granola on the side for a crunchy texture that complements each bite of cake.
  5. Herbal Tea: A warm cup of chamomile or mint tea provides soothing flavors that pair nicely after dessert.
  6. Ice Cream: Vanilla or coconut ice cream creates a delightful contrast between hot and cold textures when served together.

Common Mistakes to Avoid

Making a Flourless Orange Pistachio Cake can be simple, but there are common pitfalls to watch out for. Here are some mistakes to avoid for a successful bake.

  • Skipping the Orange Boiling: Not boiling the oranges may lead to a bitter taste. Always simmer them for an hour to soften and sweeten their flavor.
  • Overmixing the Batter: Overmixing can make the cake dense. Mix just until combined for a lighter texture.
  • Ignoring Oven Temperature: Baking at the wrong temperature can result in uneven cooking. Use an oven thermometer to ensure accuracy.
  • Not Greasing the Pan Properly: If you skip this step, the cake may stick. Lightly grease your pan to ensure easy removal.
  • Forgetting the Glaze: The honey and orange juice glaze adds essential moisture and flavor. Don’t forget this step for a shiny finish!
